monster team logs part161: Same-Day Telegram Distribution Continues

News Hook: Another monster team logs Part Drops the Same Day

On January 16, 2025, a Telegram user released monster team logs.part161, the immediate predecessor to part162 in a continuing same-day distribution run. That two files in the same series surfaced on the same day is the newsworthy angle: operators who publish numbered infostealer bundles back-to-back are clearing backlog at scale, and defenders should treat clustered releases as a single exposure event rather than isolated files.

Series Timeline and Volume

part161 contains 9,613 records, making it nearly double the size of its sequential sibling and a clear contribution to the cumulative harvest across the monster team logs series. Each subsequent release keeps the backlog fresh in the marketplace, and threat researchers tracking the channel note that same-day drops often share infection vectors or victim populations, meaning credentials in one part may correlate with those in the next.

Records and Data Exposed

The part161 file exposed 9,613 records containing email addresses, plaintext passwords, and URLs identified as API hosts. The plaintext password format removes any cracking barrier, while the API host URLs give attackers a map of authenticated endpoints that may still accept those credentials long after the initial infection.

Why Clustered Releases Amplify Risk

Same-day releases of numbered stealer parts tell us operators are either automating their publishing pipeline or responding to demand from buyers who pre-subscribe to the channel. Either way, the practical effect on victims is the same: credentials reach a wider audience faster, and any single username-password pair appearing in part161 may be combined with data from part162 or earlier parts to enrich attacker-held profiles of the same targets.

What Exposed Users Should Do Now

Treat every credential that was active on a browser or application endpoint in January 2025 as potentially exposed. Rotate passwords, enforce multi-factor authentication, revoke unused API keys, and inspect login history on SSO portals and cloud consoles for sessions originating from IPs and user agents outside your baseline. Organizations should also cross-reference their own email domains against the monster team logs cluster for signs of employee compromise.

Check Your Exposure With HEROIC

HEROIC curates more than 400 billion compromised records from infostealer logs, combolists, and verified breaches. Run an email or domain search against the HEROIC database to see whether credentials tied to monster team logs part161, its sibling part162, or related Telegram releases have been indexed, and move to remediate before attackers catch up.
